Application mea Maren a, 1922. serial No. 540,318.`

To all whom t may concern Be it known that I, IIARRY S. SPLIT-HOFF,

a citizen of the rUnited States, residingV at, Chicago, in the county ofCook and State of y Illinois, have invented new and useful Improvementsin I-Ieat Regulators for Ovens, of which the following is aspecification.

This invention relates to improvements in ovens, the general object ofthe invention being to provide means for controlling the circulation ofhotair through theoven. V Another object of the invention is to pro videa number of baffle plates which are adjustable to different positions sothat the circulation of air to the different decks can bel controlled.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter `fully described,

illustrated in the accompanying drawings and specifically pointed out inthe appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views., and in which Figure 1is a sectional view of an oven showing my invention in use.`

Figure 2 is a sectional view taken at right angles to Figure 1 andshowing one of the baffle plates 5 in raised position.

Figure 3 is a fragmentary front view` showing the means for holding thehandle 8 in adjusted position.

Figure 4 is a section on line 4-4 of Figure 2.

` some of the decks, these brackets acting as y supports for' the shafts4:. These shafts carry the baffle plates 5 which are covered withasbestos or the like, `as shown at 6;

These plates are so formed that when moved into a horizontal positionthey will close the space between the decks and the sidewalls of theoven and thus prevent the passage of heated air through such spaces.

`of the handle passes.

Each shaft has secured thereto,by means ofthe coupling 7, a handle 8which is of substantially U-shape with one limb longer than the other.ThisV long limb passes through the oven face and is coupled to the shaftand the other limb has its extremity reduced and adapted to engage anyone of a series of holes 9 formed in a dial platelO which is secured tothe oven and has a hole in its center through which the long limb bemoved out of engagement with the holes or recesses 9.

outside of the oven and that they will be held in adjusted position bythe handle and recesses.

My invention acts as a heat controlling kdevice for the oven, a heatdistrib-utor for the oven, a heat control for each deck of the oven,'adjustable baffle plates for the oven and batlie plates adjustable tofive positions, as follows:

A. Heat regulating.

B. Heat control.

C. Heat holding.

D. Heat changing on the various decks.

E. Heat releasingy It is thought from the foregoing description that theadvantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope ofthe appended claims.`

This handle is madev slightly flexible so that the short limb can PATENTema; y

l. In combination ywith an oven and its decks, brackets connected withthe side edges of each deck, a plate hinged to each bracket,

a handle connected with each plate and eX- tending through the frontofthe oven and means for holding the handle in a position p with theplate closing the space between the deck and the side wall of the ovenor for f edges of each deck, a plate hinged to each bracket, a handleconnected with each plate consisting of a plate on the front of the andextending through the front of the stove having a plurality of holestherein and oven, means forholding the handle in a pothe handle having asprin part, Vthe eX- 10 sition with the. plate closing the space be-Vtremity of which is adapte Vto engage any Y 5 tween. the deokand theside'wallof the oven one of said holes.
